I own a Mazda RX-8 with high mileage. Every so often I get snail-mail spam for an extended warranty, which I just throw out. One day, I was really bored and slightly curious about the protection, so I called them (bad form, I know). After going through a couple of menus, a friendly rep took my basic info, then frowned on his end. He regretfully informed me they don't offer warranties on RX-8s because it has a rotary motor.
So, genius, why do you keep sending me warranty offers you can't honor?
Somehow, I'm super lucky on my cell and receive maybe one spam call a month. I have no idea how many trillions of those calls go to my landline because I never check the messages and the ringer doesn't work...
